VAPORIZER FOR HYDROCARBON-BURNERS.

SPECIFICATION forming part of Letters Patent No. 713,509, dated November 11, 1902.

Application filed March 3. 1900. Serial No. 7,203. (No model.)

To all whom, it' may concern:

Beitknown that I, GEORGE D. SCOTT, a citizen of the United States, residing at Birmingham, in the county of Jefferson and State of Alabama, haveinvented certain new and useful Improvements in Vaporizers for Hydrocarbon and other Burners, of which the following is a specification.

It is the object of this invention to provide 1o a simple, efficient, and reliable means for rapidly cleaning the outlet-oritice of a vaporizer for hydrocarbon and other burners; and to this and other ends the invention consists of the improvements hereinafter described and claimed.

The nature, characteristic features, and Scope of the invention will be more fully nnderstood from the following description, taken in connection with the accompanying drawzo ings, forming part hereof, and in which- Figure 1 is a side elevational view of a vaporizer embodying features of my invention and showing it in application to one type of hydrocarbon-burner. Fig. 2 is a detail View,

in central section, of the right-hand end of the vaporizer shown in Fig. 1, illustrating cleaning means of my invention. Fig. 3 is a sectional view taken on the line 3 3 of Fig..2. Fig. 4 is a face view of the cam, showing it in 3o the same position as in Figs. 2 and 3. Fig. 5 is a view similar to Fig. 2., but showing the cleaner in different position. Fig. 6 is a sectional view taken on the line 6 6 of Fig. 5. Fig. 7 is a face view of the cam, showing its position as in Figs. 5 and 6. Fig. Sis a sectional view taken on the line 8 8 of Fig. 2, showing the passage for vapor and the like. Fig. 9 is a sectional view showing the ways in plan. Fig. 10 is a perspective view of a modi- 4o tication of my invention, showing the parts detached. Fig. 11 is a view in central section, showing the parts assembled; and Fig. 12 is a sectional view taken on the line 12 12 of Fig. 11. In the drawings, 1 is a vaporizer having an inlet 2 and valve 3 at one end and having at the other end a detachable casing provided with a discharge-orifice 4 and wit-h means for cleaning the same.

5 is a mixing-tube having a mantle 6 5o thereon.

7 is a rock-shaft having at one end means, as 8, for rocking it and having at its other end a cam 9, provided on its face with a groove l0. These parts may be located in a detachable casing 11, equipped with the discharge-orice 4, which may be reamed out on its inside, as shown, so as to guide the needle. Also located in the casing 11 is a reciprocating cross-head or carrier 12, which is pro- 6o vided with a needle for penetrating the discharge-orifice 4. and with a pin-13, adapted to follow the groove 10 of the cam 9. This crosshead or carrier works in a guide piece or ways 14, at the base of which is a passage 15 for 65 the passage of vaporized oil.

16 is a groove which accommodates the head of a set-screw that may be employed to hold the needle. It is apparent from the foregoing description and with reference to 7o lthe drawings that in order to remove carbon or other matter clogging the aperture it is merely necessary to pull the cord or chain 8, which will, through the intervention of the shaft 7 and cam 9, bring the cross-head or 75 carrier and needle into the position shown in Fig. 5, so that the needle will quickly and readily make an opening for the escape of the vaporized oil into the mixing-chamber 5, whereupon a pull of the opposite 8o cord will bring the cross-head into its normal position, which is shown in Fig. 2. In the modification shownin Figs.10 to 12 the detachable casing 11 is provided with internallythreaded extremities, as 17 and 1S, for the re- 85 ception, respectively, of a cap 19 and a guidepiece 20, slottedas at 21,which forms,as shown in Fig. 12, the ways for the reciprocating cross-head or carrier 12. In this instance the cross-head or carrier instead of being pro- 9o vided with a pin is cut away, as at 22,to accommodate a projection, as 23, on the rock-shaft 7. The cap 19 is provided with a passage 24.l for the escape of vaporized oil, which may be,

as shown, in an inclined position-that is, said passage-Way extends from the upper portion of the cap 19 downward to the dischargeorilce l, which is located in the lower side of the detachable casing and which constitutes a vapor-jet orifice. Such a passageway affords communication between the upper portion of the vaporizing-tube interior and the discharge-orifice, thus reducing the tendency of the discharge-orifice 4 to become clogged. Obviously the cap 19 constitutes what may be called a filling It will be obvious to those skilled in the art to which the invention appertains that modiications may be made in details without departing from the spirit thereof. Hence I do not limit myself to the precise construction and arrangement of parts hereinabove set forth and illustrated in the drawings; but,

Having thus described the nature and objects of the invention, what I claim as new, and desire to secure by Letters Patent, is-

1. The combination with a horizontal vaporizer having a vapor-discharge orifice in one of its side walls, of a needle located in and aorded a range of motion transversely of the vaporizer, means for reciprocating said needle, and a filling in such vaporzer having an inclined passage-Way extending from the upper portion of the vaporizer interior to such vapor-discharge orice, substantially as described.

2. The combination with a horizontal vaporizer having a valved inlet for oil and a vapor-discharge orifice, of ways ranging transversely of said vaporizer and in proximity with the discharge-orifice, of a cross-head adapted to said ways and having a needle arranged to penetrate the discharge-orifice, when the cross-head is reciprocated, means for reciprocating the cross-head, and a filling located between the cross-head and the oilinlet and having an inclined passage-way or duct extending from the upper portion of the Vaporizer interior to said vapor-discharge orivice, substantially as described.

3. In a vapor-burner a horizontal Vaporizing-t-ube having a vapor-jet orifice in its lower side, and a filling in such tube having an inclined passage-way extending from the upper portion of the tube interior to such vapor-jet orifice.

In testimony whereof I have hereunto signed my name.
